There's no money in Dutch startups, very little investment.
So with some very rare exceptions, most startups pay way less than traditional IT, and you can shout all you want about only wanting young an hungry talent willing to work for equity (also quite relative, very few Dutch startups flip or go IPO), this is seriously hampering their potential for attracting talent.
Especially in a country that may be less risk-averse than most European countries, but still way more than the US.
